资 源 简 介
Provides syntactic sugar around the libgdx physics api to enable code like this:
```
Body body1 = B2d
.staticBody()
.withFixture(B2d
.box(5, 1)
.at(0, -2)
.category(1)
.mask(2))
.create(world);
Body body2 = B2d
.dynamicBody()
.at(0, 5)
.withFixture(B2d
.circle()
.radius(0.5f)
.restitution(0.9f)
.category(2)
.mask(1))
.create(world);
Joint joint = B2d
.distanceJoint()
.between(body1, body2)
.collideConnected(true)
.localAnchorA(0, 0)
.localAnchorB(0, 0)
.length(7)
.create(world);
```
